NAME

       rfcomm - RFCOMM configuration utility

SYNOPSIS

       rfcomm [ options ] < command > < dev >

DESCRIPTION

       rfcomm   is   used   to  set  up,  maintain,  and  inspect  the  RFCOMM
       configuration of the Bluetooth subsystem in the  Linux  kernel.  If  no
       command  is  given,  or  if  the  option  -a  is  used,  rfcomm  prints
       information about the configured RFCOMM devices.

OPTIONS

       -h     Gives a list of possible commands.

       -a     Prints information about all configured RFCOMM devices.

       -r     Switch TTY into raw mode (doesn't work with "bind").

       -f <file>
              Specify alternate config file.

       -i <hciX> | <bdaddr>
              The command is applied to device -A Enable  authentication.   -E
              Enable  encryption.  -S Secure connection.  -M Become the master
              of a piconet.  hciX , which must be the name or the  address  of
              an  installed  Bluetooth  device.  If not specified, the command
              will be use the first available Bluetooth device.

       -A     Enable authentification

       -E     Enable encryption

       -S     Secure connection

       -M     Become the master of a piconet

       -L <seconds>
              Set linger timeout

COMMANDS

       show <dev>
              Display the information about the specified device.

       connect <dev> [bdaddr] [channel]
              Connect the RFCOMM device to the remote Bluetooth device on  the
              specified  channel.  If no channel is specified, it will use the
              channel number 1. If also the Bluetooth address is left out,  it
              tries to read the data from the config file. This command can be
              terminated with the key sequence CTRL-C.

       listen <dev> [channel] [cmd]
              Listen on a specified RFCOMM channel for  incoming  connections.
              If  no  channel  is specified, it will use the channel number 1,
              but a channel must be specified before cmd. If cmd is given,  it
              will  be  executed  as soon as a client connects. When the child
              process terminates or the client disconnect,  the  command  will
              terminate.   Occurrences  of  {}  in cmd will be replaced by the
              name of the device used by the connection. This command  can  be
              terminated with the key sequence CTRL-C.

       watch <dev> [channel] [cmd]
              Watch  is identical to listen except that when the child process
              terminates or the client disconnect, the  command  will  restart
              listening with the same parameters.

       bind <dev> [bdaddr] [channel]
              This  binds  the RFCOMM device to a remote Bluetooth device. The
              command did not establish a connection to the remote device,  it
              only  creates  the  binding.  The connection will be established
              right after an application tries to open the RFCOMM  device.  If
              no channel number is specified, it uses the channel number 1. If
              the Bluetooth address is also left out, it  tries  to  read  the
              data from the config file.

              If all is specified for the RFCOMM device, then all devices that
              have bind yes set in the config will be bound.

       release <dev>
              This command releases a defined RFCOMM binding.

              If all is specified for the RFCOMM  device,  then  all  bindings
              will be removed.  This command didn't care about the settings in
              the config file.
